1 Claim.

My present invention relates to doors and more particularly to automobile doors which are provided with glass window panes that can be opened and closed at the will of the occupant of the vehicle.

The elevating mechanism of the conventional type operates from the outside of the door frame adjacent the vehicle seat by means of a crank lever associated with gear mechanism there being no counterbalancing provision for the weight of the window. The result is that it takes considerable more force to raise the window than to open it. Another inconvenience is present in that the crank lever projects from the door and interferes with the lower limbs of the occupant of the vehicle in the case of a large stature person also the crank lever often catches in the clothing of the vehicle occupant when entering or leaving the vehicle.

In my present invention, I have obviated all of the above objections and have produced an automotive vehicle window mechanism which has a lever located preferably in the window sill of the door and which operates in a horizontal plane to open and closethe window. The sash of the window is counterbalanced such that it takes no more force to close the window than it does to open it. When opening or closing the window, the first application of force applied to the lever unlocks the sash and as the force is continued in a horizontal plane the window is opened or closed as the case may be, the window becoming locked in place when the force is discontinued.

The principal object of my invention is an improved automobile window mechanism;

Another object is an automobile window mechanism which counterbalances the window weight;

Still another object is an automobile window mechanism which is provided with an operating lever located in the window sill and having an operating movement in a horizontal plane with respect to the perpendicular motion of the window sash which it operates;

And still another object is the combination of a sash locking member and sash elevating and depressing mechanism which elevates or depresses the window sash and locks said sash in any position all in one operation in which the force is applied in a horizontal plane, and

Other objects and novel features comprising the operation and construction of my invention will appear as the description of the same progresses.

In the drawings illustrating the preferred em bcdiment of my invention;

Fig. 1 is a fragmentary side elevation as viewed from the inside of an automobile door a portion of the frame of the door being broken out to more clearly show the mechanism. The solid lines indicate the window sash in a lowermost position, the dot and dash lines indicating the sash and mechanism in a partially raised position;

Fig. 2 shows an inside elevation partially broken away of the window lever locking and operating mechanism being enlarged to full size proportions;

Fig. 3 is a vertical cross-section taken on the line 3-3 indicated on Fig. 2;

Fig. 4 is a full size side elevation of the counterbalancing spring mechanism; and

Fig. 5 is a vertical cross-section taken on the line li5 indicated on Fig. 4.

Referring more in detail to the drawings,

Fig. l which illustrates the inner side of the automobile door is provided with a panel ll On the inner side of the panel it and adjacent the rear end I have provided a vertical strap or hanger member ii the lower end of which is bent over at 52 to inclose the counterbalancing spring is one end of which is anchored by means of a hook M to the bottom l5 of the strap ll, as shown at Fig. 4. The inner end of the spring 33 is anchored in a slot located in a stud iii which is secured to a bell-crank lever H. The

lower arm of the bell-crank lever l'a' is c'on-' nected with the lower side of the window sash frame it by means of a link lever member IQ. The upper arm of the bell-crank lever ll is pivoted to a horizontal lever member 2E] the front end of which is provided with a vertical portion Zita upon which is mounted a slidable plate 2!. The plate ii is provided with three stud members solidly fixed in said plate 2! and having a shouldered body portion 23 adapted to engage in vertically elongated slots 2t located in the plate 28a, the plate 2! and studs 22 being held in place by the head of the studs on the back side of the plate Zfia such that the plate and studs 2i and 22 respectively may slide in a vertical manner upon each other. Solidly attached to the plate 2| at its top is a gear segment member 25 the teeth of which are adapted to engage in a rack 26 located on the bottom of a slide-way member 21 which is horizontally attached to the inner side of the door panel ill.

The plate Zlla which is a part of the lever member 20 is supported in the slide-way 21 by means of a shouldered stud 28 which is solidly secured to the plate 20a at its rear portion which is provided with a roller or shoulder 29 which is adapted to slide on the slide-way edges 21a. A spacer plate 30 is securely attached to the plate 20a and the front face of said spacer 30 engages the back surface of the slide-way 21 aligning said slide-way up with the segment member 25 the teeth of which engage in the rack provided on the bottom of said slide-way 21, the slide-way 21 being in combination with the rack 26.

An opening 3| is provided in the plate 2| the top of said opening being provided with an outstanding bracket member 32 formed from a portion of the plate 2| and extending out beyond the upper portion of the opening 3| and further adapted to receive a compression spring 33 the lower end of which is anchored on a similar projecting bracket member formed from the plate 20a and projecting outwardly through the opening 3| in the plate 2|, as shown in Fig. 3. A pin 35 is located in the bracket 34 for the purpose of maintaining the compression spring 33 in proper alignment. The spring 33 normally maintains the plate 2| in an upper position on the plate 20a and thereby keeping the segment teeth in engagement in the rack 26.

When the segment teeth of the member 25 are engaged with the rack 26 no horizontal movement of the lever 20 is possible thereby making it impossible to open or close the window sash.

For the purpose of unlocking the segment 25 with the rack 26 and at the same time providing a pull lever to operate the bell-crank lever I1, I have provided a hand lever 36 which is pivoted at 31 to the plate 20a. The lower portion of the hand lever 36 is provided with shoulders 38 oppositely opposed to each other and adapted to engage over the flatted head portion of the upper studs 22 anchored in the sliding plate 2| which carries the segment 25. A guide stud 39 is located in the upper portion of the hand lever, the shouldered portion 40 being adapted to engage in the radial slot 4| located in the upper portion of the plate 26a.

When the hand lever 36 is pulled forward or backward the first application of force pivots the lever 36 on the pivot 31 and the shoulder 38 depresses the stud 22 causing the plate 2| to slide downward disengaging the segment 25 from the rack 21 and by a continuation of the force appliedin the horizontal plane the lever 20 is slid forward or backward, as the case may be, actuating the bell-crank lever and raising the window or lowering it. The counterbalance spring |3 maintains the weight of the sash in a counterbalanced state such that very little force is necessary.

When the'lever 36 is released the compression spring 33 returns the plate 2| and segment 25 causing the segment teeth to engage in the rack 26 thereby locking the sash in any position desired.

Having thus described my invention what I claim as new is:

An improved sliding lock for window elevating mechanism comprising in combination, a plate rigidly connected with said window elevating mechanism, said plate having a plurality of elongated slots, said slots extending through the said plate and being adapted to receive shouldered studs rigidly mounted in a second plate slidably mounted on one side of said first plate, an opening in said sliding plate being adapted to receive therethrough a right-angle bracket attached to said first plate, a second bracket attached to said sliding plate adjacent one end of the said opening, a compression spring located between the opposed sides of the two said brackets for the purpose of maintaining the said sliding plate in an elevated position on said first plate, a depressed cam surface formed on the top edge of said sliding plate, a hand lever pivoted to said first plate, a cam stud solidly attached to' said hand lever, a radial slot located in the upper portion of said first plate and being adapted to receive the body portion of said cam stud, the head of said cam stud being adapted to engage the said cam surface on the said sliding plate, a tubular horizontal slide-way having one side open and teeth formed on its lower edge, a stud journalled through said sliding plate'and solidly attached to said first plate, said journalled stud being provided with a shoulder engaged with the edges of the open side of said slide-way and an enlarged fiatted head adapted to slide within said tubular slide-way, a rack engaging member solidly attached to said sliding plate below the lower toothed edge of said slide-way, said engaging member having radially disposed teeth on its upper edge and being adapted to engage with the toothed openings in said lower edge of said slide-way.
